As reported by our sister site Deadline, Acevedo has been cast as Ricardo Diaz, an ex-con who is set on taking control of Star City’s criminal underworld. Based on DC Comics’ Richard Dragon, Diaz is described as a master in hand-to-hand combat.

Previously, Arrow announced at the San Diego Comic-Con that Person of Interest‘s Michael Emerson would recur during Season 6 as a mystery character (perhaps Helix founder Cayden James?).

Acevedo most recently recurred on AT&T Audience Network’s Kingdom, playing a troubled MMA coach, and was a series regular on Syfy’s 12 Monkeys. In addition to his run as Fringe‘s FBI Agent Charlie Francis, his previous TV credits also include Prime Suspect, Law & Order: Trial by Jury, The Black Donnellys and Oz.
